Flower parts are minute except the three inner sepals which rapidly develop into conspicuous red to rose-colored wings or vanes about ½ inch wide, attached to the seed. These vanes, with their seeds, develop into compact clusters 2 inches or more in diameter. Leaves are oval or oblong, fleshy and dark green, on short stout branches which are often prostrate. Grows in plains. Blooms May-July.

This is just an ordinary dock closely related to the pest you dig from your lawn, but a good example of a common wayside weed brightening the bit of world in which it grows. That bit of world, for this particular dock, is usually an ugly one, as it seems to choose the poorest soil it can find, the cinders beside a railroad track—or the gravelly edge of a country road. No one notices the small, insignificant flower, but its hour of glory comes with the brilliant rose and red seed vanes that call out gaily to every passerby. In the plains of western Colorado another dock, Rumex hymenosepalus, is also spectacular growing to a height of 2 feet or more with a great column of rose-colored seed vanes.
